That is symmetry.

That would be asymmetry.

A lack of perception to see the symmetry that is there.
Classes create instances of the class when called.
Sometimes alternate constructors are needed when there is more than one
possible way to create an instance from a given input. In the case of
str(iterable), one could want either a string representing the iterable
itself, just as with non-iterables, or a string representing the
concatenated contents of the iterable. Str.join implements the second
choice, with an added string parameter to allow a constant string to be
interpolated between the joined items.

Yes. Mr. Shaw suffers from the same disease of 'neglect' that he
accuses others of. See my other response in this thread.
